midbrain reticular formation
Acronym: MRF
The term midbrain reticular formation (MRF) has come to refer to several quite different combinations of midbrain nuclei based on function ( Wikipedia Google AI ). Earlier definitions referred to a histologically defined composite structure found in the midbrain (MBR) of the human ( Carpenter-1983 ), macaque ( Olszewski-1952 ), rat ( Swanson-2004 ) and mouse ( AMBA-2024 ). All authors two parts of the MRF: the pedunculopontine nucleus (PPN) and the cuneiform nucleus (CNN ). Some authors also name a subpart of CNN. The names of subparts are inconsistent and, in NeuroNames are classed as synonyms of CNN..
      Activation of the MRF triggers the orienting response ( Vinogradova-2001 ) of the interrupt control system ( Bowden-2021 ). Updated 20 Oct 2025..
